Overview
The prototypes of various components of typical bridge types are modeled in the system for the purpose of generating graphical and tabular geometric reports that are used by the engineer or drafter at various stages during the preparation of bridge contract drawings.
The system generates drawings for the bridge layout, abutments, piers and foundations. The drawings depict projections for bridge elements that can be directly inserted into the contract documents. Annotations are intentionally kept to a minimum to allow for flexibility in the customization of the final appearance of the contract document. Tabular data such as co-ordinates of working points, bearing elevations, screed line elevations, etc. are presented in a table form which could be copied and inserted into other applications such as word processing, spread sheet or CAD applications. All graphical output could be viewed on line, printed to a printer and/or exported to files.
System Environment
Pro / Bridge - Geometry is modeled on standard MS Windows interface. Data input is via well organized dialog screens supported by graphic displays, examples and User's guide. It supports cut and paste to and from the system to other applications such as Word or Excel. Graphic files could be printed and/or exported to many file types including "dxf" type. To minimize input, data is defaulted by the system whenever possible. The flow of input is intuitive to any experienced bridge engineer.
Hardware and Operating System - Minimum Requirements
600 MHz Intel Pentium III processor or equivalent - Windows 2000, Windows XP or Window NT4.0 with service pack 6 - 64 MB of RAM (128 recommended) - 10MB of available disk space - 1024x768 screen resolution - CD-ROM drive
